Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed May 25, 1912. Serial No. 699,811.

To all 'ug/tom it mail conce/m Be it known that I, ARTHUR KLniNrann'r, a citizen of the United States, residing in Hoboken, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Siphons for Dispensing' Liquids, of which the following is a specification, reference being had to the accompanying d awings, which form a part hereof.

This invention relates to portable apparatus for dispensing liquids under uniform gas pressure in which the gas container is mounted directly upon the receptacle for the liquid, such as is shown in Patent No. 821,249, dated January 26th, 1906 and Iatcnt No. 943,421 dated December 14, 1909.

The object of the invention is to improve generally the construction of such apparatus.

One object is to render unnecessary the provision of auxiliary safety devices in case of abnormal gas pressure and to eliminate the excessive leakage hitherto incidental to the use of such devices by reason of the high pressure of the `gas. This is accomplishing by providing;` a container of greater volume whereby the pressure is reduced pro-- portionally and a more uniform pressure maintained during the emptying of the receptacle.

Another object is t0 provide a simple means to charge the gas container at the required gas pressure without the use of special apparat-us as heretofore employed.

A further object is to provide simple means to increase or decrease the flow of `egas from the gas container into the recepta cle while the latter is in use.

Another object is to lock positively the gas container to the liquid receptacle to prevent the loosening or partial detachment of the container therefrom, and the consequent loss of gas' and gas pressure.

Another object is t0 provide a container which, while of greater volume than heretofore, shall be of such form as to reduce rather than increase the total height of the assembled apparatus so that the same may be placed in ordinary refrigerators.

A further feature, made possible by the reduction of the gas pressure, relates to the admission of the gas intothe receptacle prior to the opening of the liquid discharge valve. This has been impossible in previous structures employing great gas pressure due to the liability of explosion. In fact, previous devices provided for the opcn ing of the draw-olf cap in advance of the gas valve. The result was that when only a simili volumeof liquid was wanted the discharge valve would be opened momentarily without, however, actliatiirglr the gas valve. The liquid desired would bc discharged under the pressure of the gas in the receptacle but no fresh gas would be admitted. This resulted in the liquid becomingr flat.

The invention will be explained hereinafter with reference to the accompanying drawing,` in which it is illustrated and in which- Figure 1 is a view in vertical section of the improved apparatus. Figs. 2 and 3 are detail views of a wedge adapted to hold the zgas valve open to permit. the charging of the container. Fig. fl is a detail view in clevation of a portion of the gas valve actuating' mechanism. Fig. 5 is a plan view of an automatic reducing valve.

The `iras container u. which is charged with jas at some nominal but adequate pressure, thirty pounds having' been found to be satisfactory and is provided with a bail u. by which the entire apparatus can be conveniently carried about, has a recessed bottom which is adapted to receive the neck of the liquid receptacle o. The entire bot tom of the container is also recessed or concaved to receive the upper portion of the liquid receptacle in nested relationship and thus lessen the height of the assembled apparatus.

About the neck 7) of the liquid receptacle may be placed an exteriorly threaded split sleeve c adapted to bear against the shoulder of formed on the neck. On the split sleeve c is threaded an annular collar (Z having lianges d engaged by bolts (l2 extending through tubes n? in the container and having heads (Z3 to bear on thc upper side of the container a to hold the latter in position on the receptacle The bolts are provided with lugs It through which may be passed a metal pin c headed on one end and provided with an eye on the other end through which a cord may be passed and sealed as at f to insure against unauthorized detachment of the `ras container. By the method of attachment explained it will be seen that the bolts Z2 serve to lock the sleeve c against the shoulder b2 of the receptacle and that the sleeve c is rotatable so that the container may besecured-thereon in any desired position toy more advantageously display the label with reference to the tap.

The container is provided with a draw-off tap g in communication with the interior of the receptacle through suitable passages as in previous constructions. In the apparatus ashcretofore constructed, the valve which controlled the flow of the gas from the container was moved in one direction by the pressure of the gas and in the other direction by manual operation of suitable actuating mechanism. It has been found preferable, however, to increase the 'size of the gas container to such an extent that the pressure of the gas will be too low to cause an explosion of the receptacle through leakage of the gas thereinto from the contamer, and hence a spring may safely be employed to seat the valve. The general arrangement of the plug z. in the container a adjacent.

to the draw-off tap is similar to that formerly employed in that it is formed at its outer end with a flange L against which the diaphragm h2 may be held by the cap i and with a seat about the mouth ofthe passage la therethrough against which the diaphragm may be pressed to prevent the passage of the gas. The chamber on the inner side of the diaphragm l?? is in communication with the top of the recept-acle b, through a tube Z which extends through a second tube m formed in the recessed portion of the bottom of the container and which projects into the neck of the receptacle. This tube m has threaded on the lower end thereof a nipple n recessed interiorly to receive an auis high, and communication is established between container azand receptacle b, there will be a rapid flow of gas through the tubeZ and the valve o will be forced toward the opening in the nipple n so as to restrict the flow of gas. With a low pressure in the container the valve 0 remains in its normal horizontal position. In this manner the flow of gas from the container to the receptacle is regulated automatically and excessive iow is prevented. It is to be understood, in view of Fig. 5, that the valve 0 is ofsuch a size with respect to its seat in nipple n and that the teeth of the valve are of such relative rigidity as to prevent the passage Z from being closed entirely under any circumstances, the valve o being moved toward its seat under increased gas pressure to check sudden inrushes of gas which might be so violent as to break the bottle b.

Somewhat loosely mounted in the outer end of the cap z' sothat it may rotate therein is a sleeve p within which is the plunger p adapted under the action of a spring 1' in the sleeve p, to bear against the diaphragm lz? and press the same against its seat to close the passage 7c. A lever s is mounted in t-he sleeve 79 and carries an adjusting screw sf which bears against the plunger 7)', its'head being exposed for adjustment outside of the sleeve p. The lever s has a lower forked arm at right angles to the arm in sleeve p which is adapted to be engaged by a toe g* carried by the .operating lever g3. A stud t carried on the valve stem g of the valve g2 of the draw-off tap g is adapted to be engaged operatively by the lever g3 to open said tap. The toe r/J is positioned with respect to the valve g2, the lever g3, the pin t and bell crank lever s so that the diaphragm 11,2 will be released from its seat to admit gas to the receptacle before the lever engages the pin t and opens the valve g2 to permit the discharge of liquid. In like manner, it will be obvious that the liquid discharge valve g2 is seated prior to the seating of the diaphragm h2. The advantage of this arrangement is that fresh gas enters the Siphon whenever the latter is used, and the liquid is discharged readily and in a solid stream, from the initial opening of the liquid discharge valve. In prior constructions wherein the liquid discharge valve was opened prior to the gas valve, the initial impulse was given to the liquid by comparatively dead gas retained in the receptacle at a low pressure. By closing the gas valve after the liquid discharge valve is closed a fresh supply of gas is alwaysintroduced into the space above the liquid in the recept-acle, thereby` preventing to a marked degree, the usual a'tness experienced with liquids contained in devices of this character. This is especially true where the contained liquid is beer or the like. When the toe g4 engages the lever s the latter swings on its fulcrum s2, compresses the spring r and moves the stud s out of engagement with the plunger p permitting the diaphragm 71.2 to move from its seatv in the passage c and allow the gas to flow to the receptacle I). This flow continues so long as the lever g3 is pressed downward suficiently, although the rate of flow, as before eX- plained, is regulated by the pressure valve o. When the lever ga is released, the spring 1 forces the plunger p to seat the diaphragm h2 and thus the How of gas is discontinued. Initial adjustment of the extent of movement of the diaphragm 71,2 may be made by the adjusting screw s which moves the crank lever .s toward or from the plunger p and thus determines its degree of movement in the sleeve p.

The container a may be charged when removed rom the receptacle b by engaging the nipple nfwith a rubber hose connected to an ordinary gasdrum through a suitable pressure regulator. Since the container permits the use of gas at a nominal pressure special apparatus and pressure reducing devices as heretofore employed are unnecessary. During the charging the valve o lies across the end of the tube Z so it is necessary that the latter be formed with a recessed or V- shaped end to permit the inflow. During the charging operation, it becomes necessary7 of course, to release the diaphragm h2 from its seat and this is done by insertin the wedge shaped implement u shown in Figs. 2 and 3, between the pin t and the forked arm of the lever s, thus forcing the latter upward and compressing the spring r. By the employment of the spring 1', the tension of which may be of any desired degree, a relief means is provided for any gas generated in the receptacle from the liquid therein contained. For instance, when filled with beer, the carbonio acid gas therein may be set free under the influence of heat and the bottle might burst unless a vent be provided therefor. ln this construction the gas will iow into the container upon reaching a predetermined pressure depending on the eii'ective force of the spring r. Then too the nominal pressure employed eliminates the dangerous gas pressures in the receptacle for liquid caused in former constructions by the inadvertent admission of gas into the receptacle prior to the opening of the liquid dscharge valve.

VWhat l claim is:

1. The combination of a liquid receptacle, a gas container, a valve to control the delivery of liquid from the receptacle, a Valve to control the delivery of gas from the container to the receptacle, a spring in axial alinement therewith to hold the same closed against the pressure of the gas in the container and in the receptacle, and to permit the valve to open automatically under excessive pressure in either vessel.

2. The combination of a liquid receptacle, a gas container, a valve to control the delivery of liquid from the receptacle, a valve to control the delivery of gas from the container to the receptacle, an operating lever to control both of said valves, means interposed between said lever and the liquid discharge valve, whereby said valve is operated, and means interposed between said lever and the gas valve whereby the gas valve is opened before the liquid valve is opened when the operating lever is moved, continued movement of the lever opening the liquid valve, and is permitted to close after the liquid valve is closed when the operating lever is returned to normal position.

3. The combination of a liquid receptacle, a gas container, an intermediate valve chamber, a gas conductor from the valve chamber to the liquid receptacle, a gas conductor from the valve chamber to the gas container, a Valve disposed within said chamber to control the. delivery of gas from the container to the receptacle and subject to the gas pressure in the liquid receptacle and to the gas pressure in the gas container, and a spring to hold the valve closed against the pressure of the gas in the container and in the receptacle and to permit the valve to open automatically under excessive .pressure ineither vessel, whereby the pressures in both vessels become equalized.
